Right click acts like Ctrl+Left click in Manager-Projects tree

Fixed in r11506

I did not apply the wxScintilla fix mentioned above since the error could be fixed in Dragscroll itself.
See  http://forums.next.codeblocks.org/index.php/topic,22807.msg155000.html#msg155000 for the wxSTC discussion.

Good. The change to scintilla is not welcome, because we want to keep it as close to the one in wx as possible.
